Doctoral thesis Memes

Imagine aliens showing up and being SHOCKED that we breathe oxygen! 😂 These extraterrestrial researchers are freaking out because what's normal for us is literally corrosive to them! Earth's atmosphere (about 21% oxygen, 78% nitrogen, and 1% other gases) would be a death trap for species that evolved in hydrogen-rich environments. The Tonian period reference? That's from 1 billion years ago when Earth's oxygen levels were still rising! These poor alien grad students just wanted to finish their PhDs and now they're discovering that our "breathable air" is basically alien acid! It's like finding out your neighbor drinks bleach for breakfast!
